Question

Determine the lateral surface area and the total surface for the pyramid. Round your answer to the nearest whole number.

Answer 1

Answer:

$L = 704$

$S = 832$

Step-by-step explanation:

Given

$H = 22$ --- Height

$W = 8$ --- Width

$L=8$ ---- Length

Solving (a): The lateral surface area (L)

This is calculated as:

$L = 2 * (L + W) * H$

This gives:

$L = 2 * (8 + 8) * 22$

$L = 2 * 16 * 22$

$L = 704$

Solving (b): The total surface area (T)

This is calculated as:

$S = 2 * (LW + WH + LH)$

This gives:

$S = 2 * (8*8 + 8*22+ 8*22)$

$S = 2 * (64 + 176+ 176)$

$S = 2 * 416$

$S = 832$
